[BUGFIX PATCH] kprobes: Use kernel_text_address() for checking probeaddress

[Masami Hiramatsu]

Use kernel_text_address() for checking probe address instead of
__kernel_text_address(), because __kernel_text_address() returns
!0 for init functions even after relaseing those functions.
That will hit a BUG() in text_poke().
